g This invention: relates to closures for glass hoppers, and the like. Hoppers of this character are quite generally used in connection .With coffee grinding machines, and.similar. pieces ofapparatus, 1 These coffeegrinding machinesare very often provided with glass hoppers, to hold: the coffee which is .to be ground; thisuconstruction adding. to the at tractive appearance. of i the ,machine,,and

also having a'utilitarian value in that the, .operator can. observe the contents of'thehop,

per: during operation of the machine.

. A hopper of-this sort is ofcou-rse provided vwith a. cover.or closure member, and. this is. i usuallyofpolished .metahand oneuof -the principal obj ects of this inventioniis ,to-provide means for mount ng a metal, or other,

cover upon, anhopper-composed of-gl'ass, or

othermaterialto which an ordinary-hinge or the like maynot be readily attached.

Another. object'of the invention is to pro vide means for attaching a cover to a-glass ;:hopper, whichis simple in. construction,

easily, applied, adapted for tight and strong connection with the-glass hopper without 1 danger of breaking .that hopper.

. Other objects and advantages I will be;- apparent from the description-thereofset out 7 below: when, takenain connection with the accompanying; drawing.

In; ,the drawing in which; like; characters ofreference designate like parts throughout the several .views thereof;

1, Fig, l is a fragmentary sectionalgwiew .through, the-upper {part of a glass .hoppjer, and; metal closure therefor, ,and theemeans for attaching the closure to the hopper; and F g; 2 1s a; fragmentary'lplan viewshow ng This means of attaching one member, to

another is of quite generalapplication, but

as illustrating a preferred embodiment-"it is shown, as stated above. in connection with a glass hopper. This glass hopper, the upper part of which is-shown in the drawing, is designated by thenumeral 10, and around the top thereof it is provided With an an largement or rib 11. It is also provided-With an upwardly eXt-ending'flange 12, around the mouth thereof, Which'fiange is adapted to receive a cooperating flange carried by the closure member 13. f

This closure member is preferably of pol .ished metal, and is also preferably of thin metal'which may be spun into'the shape 'desired. Of course thisimeinbe r maybe ofany f .othersuitablematerial. p v I ThlS closure i orico-verl .13 has to. be .so arcover the; mouth ori'nlet opening of the" hopper. Also, becauseof the considerable vibration -du-ring operation of -the device, this cover should-be .firmly, at tach'edto the hopper-so that'noise will be prevented. v

-T1I1Q1Ilf to accomplish this connection a splitiring 20 is utilized,which hasits-upper edge overturned as shown'by the numeral 21 and; its lower; edge also overturned as shown by the numeral 22, to provide a channel to receive the enlargement or rib 1 11. The opposed ends ,of vthe split ring 153? provided with lu l-gsor ears 25,, these two;.,ears .having- Zalign'e'd. I passages there- ;[in adapted to Ereceivaa threadedwbolt or screw,26;"manipulation 1015;; Which will zdraw 11. As -shown: each end. of the 1 ring is pro- '.,,vided with, aw reinforcing member, .27, each of which is fi-riji'ily attached tOzdtS respective end-,0f;'the-.'ring. 7 These may. be attached in ranged. that it maybe-readily moved to 'un- I @anyy desired-:manner, butaasishown theyflare i sold-ered or welded. J Thesereinforcing members haveattached:thereto the ears. 25. ihlsoeeach-wof these' reinforcing members has; attached thereto ani upstanding lug tor i,h i;n gel member 30,; which -are adapted -torerceive cooperatively the .1 hingemembers B1,

wh'iclriare provided with aligned-passages, ashile-the two h ngeimembers 31qa-re also (pro-v .vided with. aligned ipassages, the construction beingsuch thatthe passagesfin the two sets of members may be positioned in alignment to 'receive a hinge pin '32, one end'of Which is threaded for engagement Within one of the hinge members 31. As shown hinge members 31 are also mounted upon a rein 'forcing member 33,-,Wl1i0l1 is attached to the cover by welding or soldering, although any other suitable means of attachment may be,

used. 1

The hinge members 31 are eXtended,-as

" shown at 34, so that after the cover has been swung a proper distance, in opening movement,'th1s extension W111 contact with the reinforcement 27, or other fixed part of the hopper, to prevent further opening move ment of the cover.

By means of this construction the cover or closure may be readily mounted, in hinged relationship, upon the top of the hopper; and a neat, strong, rigid and quiet-connection is attained without danger of breaking the glass of the hopper. Also this construction lends itself to cheapness of manufacture for it is not necessary that the split ring be made with any considerable degree of accuracy since sufficient adjustment is provided to compensate for any irregularity of-sizein eitherthe ring or the enlargement 11..

While the form of apparatus herein described con'stitutespreferred embodiment of the invention, it is to be understood that the vinvention is not limited to this precise form said enlargement, overturned'edges on said ring to receive said enlargement, means for drawing the ends of said ring together to clamp said ring firmly about the saidenlargement, a hinge member'carried by said ring independent of the means for clamping the ring about the enlargement; a cover for said hopper, and a hinge member carried by said cover and pivotally connected tothe hlnge member on the said ring.

2. Apparatus of the character described comprising a hopper of frangible material such as glass or the like, an enlargement about the top of said hopper; a flexible split ring on said hopper, overturned edges on {said ring to receive the said enlargement between them, an ear carried by each end of said. ring, means for-drawing said ears toward each other to clamp said ring about "the enlargement, a hinge member independent of'said ears carried by each end of a cover for said hopper, a hinge member carried by said cover and extending between the hinge members carried by the ends of said ring, and means for pivotally connecting the said first and second named hinge members.

3. Apparatus of the character described comprising a hopper of frangible material such as glass or the like, an enlargement about the top of said hopper; a flexible split ring mounted on said hopper and having overturned edges to receive the said enlargement between them, a reinforcing member rigidly secured to each end of said ring, an ear carried by each of the said reinforcing members, a bolt for drawing the said ears toward each other to decrease the diameter of the said split ring and clamp it tightly about said enlargement, a hinge member carried by each of said reinforcements; a cover for said hopper, a hinge member carried by said cover and adapted for positioning between the hinge members carried by the said reinforcements, a hinge pin for positioning within aligned passages in the said several hinge members, to hingedly connect the said cover to the split ring; the hinge member mounted upon the said, cover being provided with an extension adapted to contact with the said reinforcingmembers to limit the opening movement of the said cover.

4. A closure for a receptacle of frangible material such as glass or the like, comprising a flexible split ring adapted to be positioned about the receptacle, a reinforcing member rigidly secured to each end of said ring, an ear carried by each of the said reinforcing members, means for clamping said said rin cars together and adapted to draw said ring tightly about the receptacle, a hinge member carried by said ring independent of said clamping means, a cover member adapted to lit the-receptacle, a hinge member carried by said cover, and means for pivotally c'onnecting said first and second-named hinge members. v

In testimony whereof I hereto aflix my signature.
